Single ion addressing is a major challenge for building a trapped ion quantum computer. We propose a novel single ion addressing scheme which allows simultaneous manipulation of multiple ions. This newly developed scheme will enable us to perform arbitrary operations on each ion in the trap simultaneously. This will enable the generation of entanglement between ions in an arbitrary subset of all ions in one trap. The addressing scheme is implemented via an array of fibers where each fiber is imaged onto a single ion. Adjustment to the ion spacing is performed with a micro mirror array, where each fiber output beam hits a single mirror of the array. A telescope between mirror array and objective forms the laser beam such that we can get spot sizes of around one micrometer, smaller than the inter-ion distance. Timing control is obtained by a separate fiber AOM for each fiber output, providing full phase, intensity and frequency control.
